The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s on the cards for Karramarro over the next couple of weeks.
It’s a bit of a slow start, to be honest. The first few days are looking pretty weak. Thursday the 10th has a bit of swell, but it’s messy and cross-onshore, not really worth getting excited about. Friday and Saturday are small and gutless, with the energy just not there. You’d be fighting for scraps.
The waiting game starts to pay off on Sunday the 13th. The swell builds to a cleaner 4ft with a longer 13-second period, and the morning is glassy. The energy reading jumps to 612, which is a solid kick. It’s a promising start, but the afternoon gets a bit lumpy and full.
Monday the 14th morning is another good call, with 4ft of clean, glassy surf and a period of 12 seconds. It’s still not huge, but it’s clean.
We have a bit of a dry spell mid-week, with Tuesday and Wednesday looking poor, though Thursday the 16th does have size (6ft) but it’s coming with a short 8-second period and a cross-off wind that, while keeping it clean in the morning, will be on the bumpy side. Friday the 17th pushes 5ft but it gets windy, and that’s more about battling the elements than having a good time.
The real standout, the one to circle on the calendar, is Monday the 21st. The conditions align beautifully. We’re looking at a strong 10ft of swell from the NW with a long 14-second period, and it’s completely glassy in the morning. The energy is massive at 2760. This is the pick of the entire window—a proper, powerful day for the experienced crew. It’s big, so it’s not for beginners, but for those who know what they’re doing, this is the day. The afternoon backs off a bit to 8ft but stays clean-ish.
Tuesday the 22nd is still fun, with 5ft and clean conditions, but the magic fades from there. The rest of the week, from Wednesday the 23rd into the 25th, looks like it fades into small, weak surf, barely breaking.
So, that’s the story. It starts slow, gets good for a stretch, and then backs off. The main events are the 13th-14th for a clean, moderate wave, and then the 21st for the big, powerful session. Don’t hold your breath on the 10th or 11th, but don’t write the whole thing off either.
Rusty out.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
